The Book of Faith
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، عَنْ حَمَّادِ بْنِ سَلَمَةَ، بِهَذَا الإِسْنَادِ وَزَادَ ثُمَّ تَلاَ هَذِهِ الآيَةَ { لِلَّذِينَ أَحْسَنُوا الْحُسْنَى وَزِيَادَةٌ}Hammad b. Salama narrated it on the same authority and added:He then recited the verse:" Those who do good will have the best reward and even more" (x)
